Anoop,

Yes you would, it's the same as if you just connected 1 switch to 2 seperate core switches, this also would create a switch loop.

Re: Switching loop in Stack switch

if you interlink the two 3560's via the stack cable - then become 1 logical switch, even though they are 2 physicals switches.

You can have multiple uplinks to your core switches, STP will recognise the switch stack as 1 logical switch - there will be no switching loop.
